Abstract
The utility model relates to a carbon brush device of a motor of a dust collector, which comprises a carbon brush, a carbon brush holder (1) and a carbon brush holder support body (5) fixed on a motor housing (6), wherein the carbon brush holder (1) is fixed on the carbon brush holder support body (5), the carbon brush is placed in the carbon brush holder (1), and the carbon brush device is characterized in that an opening which is communicated with the inner cavity of the motor housing (6) is arranged at one end of the carbon brush holder (1), a metal cover plate (3) is covered at the other end of the carbon brush holder (1), a gap (2) for facilitating the circulation of air from the side surface of the carbon brush is arranged on the metal cover plate (3), and the gap (2) is communicated with the opening at one end of the carbon brush holder (1). Compared with the prior art, the carbon brush device has the advantages that the inner cavity of the motor housing is communicated with the gap via the opening at one end of the carbon brush holder and the spaces on the two sides of the carbon brush in the carbon brush holder, so that air flow of the motor housing can flow from the inner cavity of the motor housing to the inner cavity of the carbon brush holder and further flow out of the gap, and the motor and the carbon brush can further play the better heat radiation role.
Description
Technical field
The utility model relates to a kind of motor of dust collector technical field, especially refers to a kind of carbon brush configuration of motor of dust collector.
Background technology
Existing a kind of patent No. is 200510014911.0 and is called that the Chinese utility model patent of " fixture of vacuum sweeper motor carbon brush assembling " discloses a kind of fixture of vacuum sweeper motor carbon brush assembling.Its structure comprises from the periphery of the installing hole of motor housing and prolongs certain distance to the center position of installing hole, and the elastic hook more than at least one pair of of motor housing interior curve; The leading section of cradle support has the hook platform corresponding with elastic hook; Wherein elastic hook formation of correspondence each other on installing hole.This invention has prevented that the carbon brush assembly from the rocking of motor housing, fixing the carbon brush assembly more easily.But this carbon brush support is sealed carbon brush and spring wherein, is unfavorable for the heat radiation of commutator and rotor, so its structure also needs further to improve.
Summary of the invention
The utility model technical problem to be solved be provide to above-mentioned prior art present situation a kind of simple in structure, design is ingenious and help the carbon brush configuration of motor radiating.
It is the carbon brush configuration of this motor of dust collector that the utility model solves the problems of the technologies described above the technical scheme that is adopted; The carbon brush configuration of this motor of dust collector; Include carbon brush, carbon brush holder, be fixed on the carbon brush holder supporter on the electric machine casing, said carbon brush holder is fixed on the carbon brush holder supporter, and said carbon brush places carbon brush holder; It is characterized in that: an end of said carbon brush holder is provided with the opening with the electric machine casing intracavity inter-connection; The other end at carbon brush holder is stamped metal cover board, and said metal cover board is provided with is convenient to the breach of air from the circulation of carbon brush side, and this breach is connected with the opening of carbon brush holder one end.
As improvement, said breach has two, and these two breach are arranged on the both sides of metal cover board symmetrically, makes air communication in the electric machine casing inner chamber cross the space that is arranged in carbon brush holder carbon brush both sides and is connected with breach.
Improve, the end of said carbon brush holder is provided with card again, and said metal cover board is provided with the draw-in groove with the corresponding buckle of card, and said carbon brush holder passes draw-in groove through card and is connected together with metal cover board after the bending.
Compared with prior art; The end that the utility model is employed in carbon brush holder is provided with the opening with the electric machine casing intracavity inter-connection; The other end at carbon brush holder is stamped metal cover board; Said metal cover board is provided with is convenient to the breach of air from the circulation of carbon brush side, and this breach is connected with the opening of carbon brush holder one end.The advantage of this structure is: make the electric machine casing inner chamber through carbon brush holder one end opening again in carbon brush holder space, carbon brush both sides be connected with breach; The air-flow of electric machine casing can have outflow from breach again from the inner chamber of the motor casing carbon brush holder inner chamber of flowing through like this, thereby makes motor and carbon brush play better thermolysis.
